The correct answer is option C: Lithosphere, Asthenosphere.
The layer of the Earth made up of the Continental Crust, Oceanic Crust, and the very top of the mantle is called the lithosphere (A). The lithosphere is made up of the tectonic plates that float or move on another layer of the Earth called the asthenosphere (B). The asthenosphere is a partially molten, semi-fluid layer of the Earth's upper mantle. It is in the asthenosphere that the tectonic plates are able to move and interact with each other due to the weak and pliable nature of the rock.
